For many purposes we can treat propane

c3h8 as an ideal gas at temperatures above its boiling point of

−42.°c suppose the temperature of a sample of propane gas is raised from

27.0°c to 42.0°c, and at the same time the pressure is decreased by

5.0%

does the volume of the sample increase, decrease, or stay the same? increase
decrease
stays the same
if you said the volume increases or decreases, calculate the percentage change in the volume. round your answer to the nearest percent.
%

The volume increases by 11%

Explanation:

When the pressure is decreased, the volume must definitely increase, to maintain the same pressure, the temperature must then also be increased as we see in the question. The volume was increased just as the pressure decreased and the temperature had to be increased to maintain a constant pressure. We have applied the general gas equation in solving the problem.

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
